摘要
通过秸秆腐解试验研究黑土无机纳米粒子对玉米秸秆腐解过程中水溶性化合物含量和C、N元素组成的影响。结果表明:在腐解初期,纳米粒子处理的水溶性有机化合物(WOM)、水溶性小分子有机化合物(WLOM)和水溶性胡敏酸(WHA)的含量分别高出对照21.9%,2.8%,18.3%,随着腐解进行,黑土无机纳米粒子显著抑制了三者含量;在腐解的前期,黑土无机纳米粒子对水溶性有机化合物(WOM)总C量无显著影响,降低了WHA的C含量,提高了WLOM的C含量。在腐解中后期,黑土无机纳米粒子降低了水溶性产物(WOM、WHA、WLOM)的C含量。在整个腐解时期,黑土纳米粒子降低了WOM和WHA中的N含量,而对WLOM含N量无显著影响。
The effects of the soil inorganic nanoparticles（SINP） on watersoluble products in the corn stalk decomposing process were deserved in this paper.The results indicated： In the prime decomposing process,SINP increased the content of watersoluble organic material（WOM）,watersoluble little organic material（WLOM） and watersoluble humic acid（WHA） by 21.9%,2.8% and 18.3% respectively,then inhibited the content of them.In the former decomposing process,SINP had no influence on the content of WOM,but decreased the carbon content of WHA and increased the carbon content of WLOM.And SINP inhibited the carbon content of WOM,WHA and WLOM in the middle-latter decomposing process.SINP decreased the nitrogen content of WOM and WHA in the whole decomposing process,while had no significant influence rule on WLOM.
